Declare a file pointer called input. Open a file called location.txt for reading using this pointer. If the file is not available, display "File does not exist.". The content of the text file location.txt is as shown below. It includes the location, latitude and longitude values. FILE location.txt CONTENTS UTM 1.5523763 103.63322 KLCC 3.153889 101.71333 UM 3.1185 101.665 UMS 6.0367 116.1186 UNIMAS 1.465174 110.4270601 Ask the user to enter a location. Check if the user’s location can be found in the text file. If found, display the location, latitude and longitude as shown below. SAMPLE OUTPUT Enter a location: UM Location : UM Latitude : 3.1185 Longitude : 101.6650 Otherwise display "Sorry, location could not be found". SAMPLE OUTPUT Enter a location : MMU Sorry, location could not be found

python function that creates and saves data in a file. the saved data represents exam grades. in the function , you will create n random numbers in the range 1-100, where n is the number of students. The function can be called as follows: createFile(filename, n) main function, in which the user inputs the file name and the number of students, then the main calls function createfile. the main should preform validation for n (should be > 0), and the filename(should end with .txt)

1. Write a program named program61.py This program will have three functions, the main() create() and retrieve(). main() will call: create() and main() then calls retrieve() create() will prompt the user to enter any number of course name | grade values. The course name ,AND calculated class GPA ( not the class grade ) are the written one value per line to a file named grades.txt ( review example of grades.txt below! ). Pressing Enter with no input value on the course name will exit the loop, close the file, print "File was created and closed" and return the bool value True to the main(). See Simple GPA Tip below. retrieve() will open and read grades.txt. The function then will print the course names and Class GPA as shown below. The average of all class GPA values should be calculated and displayed to two decimal places and then return variable used for the GPA average to the main() . See sample run below in which 2 course names were entered, but note that more or fewer...

Open the project or solution named mpg in this folder: ex_starts\ch07_ex1_mpg Review the code and run the program to refresh your memory on how it works. Notice that, unlike the program in this chapter, this program lets the user perform more than one calculation, it stores the values the user enters in a text file, and it displays the total miles, total gallons, and average miles per gallon when the program starts and after each entry. Add a function that calculates the miles per gallon Define a function named calculate_mpg() before the main() function that calculates the miles per gallon. This function should accept two double values for the miles and gallons, round the result to two decimal places, and return the result as a double type. Modify the code in the main() function so it uses the calculate_mpg() function. Note that the miles per gallon is calculated in three different places. Move the definition for the calculate_mpg() function after the main() function. When you run...

1. Create a file that contains 20 integers or download the attached file twenty-integers.txttwenty-integers.txt reads:12 20 13 45 67 90 100 34 56 89 33 44 66 77 88 99 20 69 45 20 Create a program that: 2. Declares a c-style string array that will store a filename. 3. Prompts the user to enter a filename. Store the file name declared in the c-string. 4. Opens the file. Write code to check the file state. If the file fails to open, display a message and exit the program. 5. Declare an array that holds 20 integers. Read the 20 integers from the file into the array. 6. Write a function that accepts the filled array as a parameter and determines the MAXIMUM value in the array. Return the maximum value from the function (the function will be of type int). 7. Print ALL the array values AND print the maximum value in the array using a range-based for loop. Use informational messages. Ensure the output is readable.
